The Controlling and Management software module development of simulating network control based on ICMP
Abstract
With the advance of network technique, internet communication is becoming more and more important. However, it can not be realized without network protocol, which is a set of rules for transmitting and managing information. Through these rules, each computer can communicate with each other. At present, a lot of basal protocols have been nearly perfect, such as TCP、UDP、ICMP, which are based on the IP packets (IP head + TCP/UDP/ICMP head + data). The main task of Control Module is to manage and send the control information, which is to simulate a set of self user-defined rules and realize simple network control on the basic of ICMP protocol. The concrete realization is that we first establish a dialog-box project through VC 6.0, and then use RAW SOCKET technology to complete the sending and receiving of ICMP packets whose data part can be used as the carrier helping realize the protocol. It means that we can use the form of IP head + ICMP head + data (simple user-defined protocol) to realize the correspondence among different computers to achieve the goal of net-controlling. Through the test, the module has realized the management and transmission of control information.
